Multi-pixel photon counters (MPPCs) are coupled on all surfaces of the scintillation crystal block segmented 3 dimensionally into cubes. No reflector is inserted into the crystal block so that scintillation light spreads to all surfaces and is detected by all MPPCs. Previously, we presented a study comparing a block composed of small cubic scintillator elements and a block consisted of a monolithic scintillator segmented by laser processing technique. In order to analyze optical condition inside the laser processed crystal, we proposed the third approach: a block with stacking scintillator plates segmented 2 dimensionally by laser. This approach involves secondary benefit of increasing a yield rate of laser-processed blocks. Because we got sufficient performance for the segmentation into 2 x 2 x 2 mm3, we examined a higher-resolution X'tal cube using scintillator plates segmented into 1 x 1 x 1 mm3 cubes.\n\\nMethods: We stacked 18 of LYSO plates with dimensions of 18 mm x 18 mm x 1 mm for the crystal block. Each plate was segmented to 18 x 18 array by the laser processing. The condition between the plates was air. 4 x 4 MPPCs of 50 micrometer type were coupled onto each surface of the crystal block. We used 22Na sources and selected the events caused by 511 keV gamma-rays by setting an appropriate energy window. Segment identification performance was evaluated in a 3D position histogram in which each segment response is appeared as the results of the Anger-type calculation using all MPPC signals. \n\\nResults: Although there were a few overlapped segments, most responses were clearly identified. \n\\nConclusions: We evaluated performance of the X'tal cube PET detector of 1 mm cubic segments based on a stack of laser-processed scintillator plates.","subitem_description_type":"Abstract"}]},"item_10005_description_6":{"attribute_name":"会議概要（会議名, 開催地, 会期, 主催者等）","attribute_value_mlt":[{"subitem_description":"Society of Nuclear Medicine and Molecular Imaging's (SNMMI) 2013 Annual Meeting","subitem_description_type":"Other"}]},"item_access_right":{"attribute_name":"アクセス権","attribute_value_mlt":[{"subitem_access_right":"metadata only access","subitem_access_right_uri":"http://purl.org/coar/access_right/c_14cb"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Inadama, Naoko"}],"nameIdentifiers":[{"nameIdentifier":"641096","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Hirano, Yoshiyuki"}],"nameIdentifiers":[{"nameIdentifier":"641097","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Nishikido, Fumihiko"}],"nameIdentifiers":[{"nameIdentifier":"641098","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Murayama, Hideo"}],"nameIdentifiers":[{"nameIdentifier":"641099","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Nitta, Munetaka"}],"nameIdentifiers":[{"nameIdentifier":"641100","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Yamaya, Taiga"}],"nameIdentifiers":[{"nameIdentifier":"641101","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"稲玉 直子","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"641102","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"平野 祥之","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"641103","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"錦戸 文彦","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"641104","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"村山 秀雄","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"641105","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"新田 宗孝","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"641106","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"山谷 泰賀","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"641107","nameIdentifierScheme":"WEKO"}]}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"eng"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"conference object","resourceuri":"http://purl.org/coar/resource_type/c_c94f"}]},"item_title":"Performance of the X'tal cube PET detector using 1 mm thick scintillator plates segmented to 1 x 1 mm2 by laser processing","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Performance of the X'tal cube PET detector using 1 mm thick scintillator plates segmented to 1 x 1 mm2 by laser processing"}]},"item_type_id":"10005","owner":"1","path":["29"],"pubdate":{"attribute_name":"公開日","attribute_value":"2013-06-25"},"publish_date":"2013-06-25","publish_status":"0","recid":"65056","relation_version_is_last":true,"title":["Performance of the X'tal cube PET detector using 1 mm thick scintillator plates segmented to 1 x 1 mm2 by laser processing"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-05-15T21:04:34.089446+00:00"}
